Frequently Asked Questions
What black and white conversion methods are available?
We offer 8 conversion methods: Standard Grayscale (classic luminosity-based), High Contrast B&W (stark threshold), Luminosity (film-like), Average RGB, Red/Green/Blue channel extraction, and Sepia tone for a vintage look.
What's the difference between grayscale and luminosity?
Standard Grayscale uses the default luminosity weighting based on human perception. The Luminosity method uses the Rec709 formula for more accurate, film-like results that match how professional video and cinema handle black and white conversion.
What do the channel extractions do?
Channel extractions (Red, Green, Blue) create a grayscale image using only that specific color channel. This can produce dramatically different results depending on your image - for example, red channel extraction makes red objects lighter and blue objects darker.
Can I convert multiple images at once?
Yes! Upload multiple images, select your preferred conversion method, and download them all individually or as a ZIP file. The conversion is applied to all images simultaneously.
Are my photos safe?
Absolutely! All processing happens locally in your browser using WebAssembly technology. Your images are never uploaded to any server - they stay completely private on your device.
What image formats are supported?
You can convert images in AVIF, Animated PNG (APNG), BMP, GIF, HEIC/HEIF, ICO (Icon), JPE, JPG, JPG (JPEG), MP4 (Video), PBM, PGM, PNG, PNG 24-bit, PNG 32-bit, PNG 8-bit, PNM, PPM, PSD, RAW formats (CR2, CR3, NEF, ARW, DNG, ORF, RAF, etc.), SVG, TGA (Targa), TIFF, WebP, XCF. Output formats include AVIF, BMP, GIF, JPG (JPEG), PNG, SVG, TIFF, WebP.
What is the Sepia effect?
Sepia creates a warm, brownish-toned vintage effect reminiscent of old photographs. It first converts the image to grayscale, then applies a sepia tone filter for that classic antique look.
Is there a file size or quantity limit?
No, there are no file size or quantity restrictions. All processing happens locally in your browser, so larger files or batches may take longer depending on your device's performance.
